// offsetof() and friends
// <stddef.h> in GCC 3.0/3.1 has the obscure property of redefining
// offsetof every time it is included, not just the first time.
// Therefore we do the same thing here, and make sure that this file
// gets included after each include of <stddef.h>.
#undef offsetof
#if defined(__GNUG__)
#define offsetof(type,ident) ((long)&(((type*)1)->ident)-1)
#else
#define offsetof(type,ident) ((long)&(((type*)0)->ident))

#define offsetofa(type,ident) offsetof(type,ident[0])
